Abstract Sixteen miles (26 km) of carbon steel (CS) sheet piling (12-mm thick ASTM A3281 cold rolled) used for docks, bridges, and bulkheads in the Duluth Superior Harbor (DSH) in Minnesota and Wisconsin are corroding at an accelerated rate of 3 mm/y or higher. The corroded pilings have an orange rusty appearance characterized by tubercles (i.e., corrosion products and deposits covering areas of localized corrosion). Barrier coatings provide one option for protection of extensive structures in fresh water, and nine coatings were evaluated for corrosion protection of CS coupons and I-beams around DSH after 46 and 35 months, respectively. Part 1 (September 2012 MP) described the coatings used and the locations of coupons and I-beams. Part 2 discusses the results of the evaluation.
